DTECH 6ft DB9 to DB9 RS232 Serial Cable Male to Male Simple Null Modem Cord Cross TX RX line 2 Pin Crossed Without Handshake for Computer Data Communication (6 Feet, Black)

Simple Null Modem Cable without handshaking: direct communication between 2 Data Terminal Equipment DTE devices using RS-232C serial communication protocol. If your equipment require 3 wire null modem cable (data lines TX, RX and GND signal ground ), 6 foot 9 pin serial cable adapter is what you need, enables you to add your peripherals to an application or replace the cables. (Note: this male to male crossover cable work by only wiring the transmit and receive lines crossed - TX to RX, RX to TX; other control lines like RTS CTS are not cross-linked, not a loopback handshake null modem cable, neither a full handshake null modem cable.) Connecting RS-232 devices for serial console access:for the proxySG, advanced secure gateway, content analysis, reporter, management center hardware devices, touchscreen, telescope, vinyl cutting machine, GPS, network equipment, radio transceiver, stereo system subwoofer, speaker set, sewing machine, weather station or controller to a remote control camera... Black DB9 serial cable male to male is with gold plated pins for superior corrosion resistance, ensuring a solid basic null modem cable connection. The connectors are equipped with a pair of thumbscrews for securing the plug to the female socket. It is shielded with standard Foil-Al layer shielding as most crossover serial cables do, it fits for most of jobs. But if there are big mess of interference at your work area, you may need a special heavy duty DB9 cable that features copper braided + AL-foil double shielded layer. Connectors: DB9 to DB9 (Male-Male) Pinout Configuration: Basic crossover of TX and RX lines, suitable for simple data transfer Interface Surface: Nickel-plated Pins Surface: Gold-plated Wire Gauge: 30 AWG DB9 Cord Diameter: 6mm DB-9 Cord Length: 6 ft (2 meter) What’s Included: 1 x Serial to Serial Cable 6’ Male to Male 1 x Manual

• Simple serial null modem cable 3 wire crossed without hardware handshaking: connects 2 DTE devices with COM port RS-232 compatible interface (Not for 15 pin 3 row computer monitor VGA-video)
• 9 pin 2 row crossover serial cable is wired as DE9 serial Null-Modem cord that 2-3 line are crosslinked (only TX/RX data and signal ground wires connected); standard shielded rs232 cord with AL foil
• DB9 male to male connector on each end equipped with screws to ensure an easy and solid connection for stable serial cross over data communication
• The wires inside are of 30AWG gauge and easy to solder to, and they connect to the pins in the order of the standard wire color code (6ft crossover serial cable, not VGA video cable)
• 6 feet short serial adapter for hooking up PC laptop, desktop computer, switch hub, router to transfer file, share resource, establish a direct serial communication link, debugging and testing, etc.
